Title: Filter system for nuclear power plant
Inventor: OTANI TAKU
IPC: G21F9/06
Filed: 1989-06-23
Abstract: PURPOSE:To effectively remove highly radioactive cruds by cleaning and removing the highly radioactive cruds captured on the surfaces of filter elements consisting of a multilayered structure with impulsive water or gas. CONSTITUTION:A waste water 8 overflowing form a side bunker pool 1 to a skimmer surge tank 6 is run in a circulating line 32 by a decant pump 33 and is transferred through a pool water inlet valve 34 to a filter device 30. The radioactive cruds incorporated into the pool water 8 by a filter element bundle 31 in the device 30 are removed. While the differential pressure of the filter element bundle 31 increases as the cruds are captured, the element surfaces are cleaned by back washing to remove the captured cruds when the differential pressure attains a specified value. The filter element bundle 31 is thereby regenerated. At the time of the back washing valves 34, 36 are closed and a valve 38 is opened to supply a gas for pressurization from a gas line 20 for pressurization to pressurize a tank 19. The impulsive pressurized water is passed in a reverse direction by repeating the opening and closing of a valve 18.

Title: Double deck video recording device and method
Inventor: JIYON OO RAIAN
IPC: G11B15/02
Filed: 1989-06-23
Abstract: PURPOSE: To prevent a video signal with a copy protection signal from being used for recording by deciding existence of a signal part selected beforehand by generating a inhibit signal to hinder a recording means from copying the video signal in response to a detector. CONSTITUTION: A detector 48 transmits an energization signal to one of input terminals at gate 52 and responds to the existence of a copy protection signal in this output. When a recording mode control, for instance, is in the internal recording mode, the energization signal is supplied to another input terminal at gate 52 and as a result, the gate 52 generates an energization signal introduced into one of input terminals of OR gate 57. The OR gate 57 responds to the energization signal and generates an inhibiting signal led to a recording means 61, and the recording means 61 responds to it and hinders the video signal directly supplied to the recording deck from being recorded. Thus, the copy protection part can be removed before a video signal is introduced into the recording means 61.

Title: Arc welding power source
Inventor: TERAYAMA KIKUO
IPC: B23K9/06
Filed: 1987-06-26
Abstract: PURPOSE:To use elements with low pressure resistance and to ensure the regeneration of a welding arc by providing a switching element driving circuit to control ON-OFF without interruption at the same time and alternately with the elements in opposition of switching elements as a couple. CONSTITUTION:The switching element driving circuit 10 controls ON-OFF of the switching elements 7a and 7b or 7c and 7d without interruption respectively so that conductive periods are overlapped materially. Namely, when a signal S2 is outputted at the same time when a signal S1 is shut off, the elements 7a and 7b which have been continued till then are not immediately shut off but shut off after some time delay by the existence of the signal S1. Then, the switching elements 7c and 7d are continued after some delay time by the signal S2 but since this delay time of continuity is shorter fairly than the delay time of shutting-off, this period can be maintained as the time when the whole switching elements are continued. Accordingly, a combination of a pulse generator 101 with an inversion circuit 102 capable of adjusting the pulse width and period without necessitating a complicated circuit is desirable.

Abstract: PURPOSE:To display a fuse function by ensuring its reliability, at a low cost and surely without a need for a specific process among standard processes by a method wherein a resistance which connects a first interconnection metal to a second interconnection metal via contacts is formed and the central part of the resistance is formed of a thin part which forms an acute angle to low- resistance parts of the contact parts. CONSTITUTION:Contacts 12, 12 are installed respectively on opposite Al interconnections 10, 10; the interconnections are connected by low-resistance parts 13, 13 and a high-resistance part 11 of polysilicon. The high-resistance part 11 forms an acute angle to the low-resistance parts 13, 13. Thereby, an electric field is concentrated very much in parts 14, 15 and also a heat value is concentrated. Consequently, the parts are especially easy to blow. When blowing parts are easy to cause at the specific parts in this manner, it is possible to reduce an energy required for a blowing operation. When such a fuse is used, it is not required to add a specific process newly. Even the fuse of only several bits can be formed in a sufficiently good cost-to-performance ratio and at a low cost.

Title: Shuttle for sewing machine
Inventor: TAKAKU KAZUO
IPC: D05B57/14
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To make a shuttle unlubricatedly usable for a long time, by covering the surface of one of a guide groove of the rotating hook or a guide protrusion of the rotating hook bobbin case holder by a composite layer which is made by dispersing fluororesin into nickel-phosphorous and forming the other surface to be slid thereon by synthetic resin. SOLUTION: Both a rotating hook 5 and a rotating hook bobbin case holder 16 are constituted of a carburization quenched and tempered steel material. A cover layer of nickel-phosphorus-polytetrafluoro-ethylene is formed on the surfaces of the rotating hook 5 including a guide groove 14 and on the rotating hook bobbin case holder not including a protrusion 17. The nickel-phosphorus- polytetrafluoroethylen cover layer is made by dispersing fluororesin particles such as polytetrafluoroethylen particles in an electroless plating bath comprising nickel-phosphorus and heat treating to form a composite layer. The guide protrusion 17 of the rotating hook bobbin case holder is formed of synthetic resin such as polyamide resin. Thus the abrasion amount and the friction coefficient of the shuttle can be kept for a long time even under an unlubricated condition.
